IMPROVEMENT IN SOLDERING-IROhI.

:ro ALL 4WHQM 1T MArcoNcnnN:

Be it known that I, THEODOE BEARDSLEY, of Springfield, Hampden county, Commonwealth `of Massachusetts, have invented a. new and useful Improved Solderinglrong and I do hereby declare that the following is a. full and exact description thereof, reference being had to the accompanying drawings, and t0 the letters of reference marked thereon. In the drawings-w i Figure 1 is a side sectional view of one half of the iron, and Figure 2 asimilar view of the other half.

The object of this invention is to obtain a soldering-iron which shall contain the heatingfap'plaratus withinl itself, and thus make4 the tool far more convenient, doing away with the heavy and awkward furnace now in use.

To vaccomplish this, I -forno myu device as I will now describe. Y In the handle, which is hollow, is a reservoir of oil, or other suitable burning-fluid, from which a wick extends through the hollow rod to the iron where the burner is placed, so as to heat the iron in the most thorough manner.' In the drawings, ig.'1 shows the interior of the handle having the oil. In this it is seen that a hollow rod, A, connects the front end of the handle B with the rear end of the small furnace around the iron point C, the rod being represented as broken off in tig. 1, and continued in tlg. 2. Extending backifror the iron point C is a cylindrical case, D, perforated with a suitable number of holes, a a a, to allow the free circulation of air. In the centre of this isthe burner E, upon the continued end ofthe hollow'rod or tube A, which has attached upon it, just behind the burner, Ya cylindrical piece, F, connected with the rod by means ofsmall connecting-rods b b, ttc., shown by dotted lines. Thisallows the aiuto circulate freely around the tube A, and to enter the case D at the rear end. The case D fitsiclosely over the cylinder F, at its rear end, the cylinder F having aprojectio'n, c, upon its circumference, which enters a slot cut into the end' of the case D, and prevents the latter from turning. In o'rder to form a regulating-device for lthe intensity of the l'lameat the burner, I place in the-handle, extending through from the rear end of the same, through the hollow tube A, to the burner, a rod G, having at its front end aconical cap, H, which fits, when drawn in, into a conical seat formed in the end of the burner. By closing or opening the valve so formed, a graduation of the ame can be e'ected, and the same entirely extinguished if desired. The device for operatingthis rod consists in an adjusting-nut, I, at the rearY end of the handle. This works upon the threads upon the end of the rod G, so as to push out or draw in the latter. A square socket, e, in the endof the cap K, uponthe end ofthe handle, preventsthe rod G from turning when the nut I .is operating upon it, th'e latter being formed so that it may turn, but have no lateral motion.y

Thecap K is screwed upon the rear end of the handle, and is packed with cork, or other suitable material. This cap is taken oif when itis desired to till the reservoir with oil.

The nick L is generally cylindrical, s that the partin the tube A may surround the rod G.- By this arrangement I obtain a soldering-iron which can be Vkept at ,any desired heat, containing all the heating-device within itself, making it a convenient tool to be carried about, and dispensing entirely with the furnace usually used for the purpose ot'vheating tho irons'. l Y

I am aware of the patent of A. N. Burbank for improvement inheatng soldering-irons, February 111860, but I do not claim the means usedf by him.

Now, having described my invention, what I claim as new, and desire tc secure by Letters Patent is- 1. A soldering-iron, in which the point is heated by a flame fed by a reservoir of fluid contained in the handle of theinstrumcnt. i

2. The combination of thc valve IL, reservoir B, and head C, substantially as and for the purpose set forth.'
